Bringing Up Baby (1938)
Number 195 on IMDb's Top 250

David Huxley (Cary Grant) is a paleontologist beleaguered by problems: he is trying to assemble the skeleton of a Brontosaurus but is missing one bone (an "intercostal clavicle"), he is about to get married, and he must make a favorable impression upon Mrs. Random, a wealthy lady who is considering whether to give a million dollars to his museum. The day before his planned wedding, David meets Susan Vance (Katharine Hepburn), a free-spirited young lady and Mrs. Random's niece.

Susan's brother has sent her a leopard from Brazil, "Baby," which she is in turn supposed to give to her aunt. Because Susan believes David is a zoologist rather than a paleontologist, she asks him to her country home in order to help her take care of Baby. Complications arise as Susan decides that she has fallen in love with David, and endeavors to keep him at her house for as long as possible. Then the plot becomes further entangled as Susan's dog, George, steals and buries the last dinosaur bone that David needs for his skeleton. Susan's aunt arrives, unaware of who David is and mistakenly believing that he is a man named Bone. Hilarity ensues when Baby runs off, as do George and a leopard from a circus that is playing in a nearby town. Susan and David must find Baby, the dog, and the dinosaur bone, try to escape from the county jail in which they've been mistakenly locked up, and ensure that Mrs. Random still wants to give away the million dollars.

Trivia: Susan pretends that she and David (Cary Grant) are gangsters. The underworld nickname she gives police for David is "Jerry the Nipper", a nickname that Jerry (Grant) had in The Awful Truth (1937). David protests to the police, "Officer, she's making it up from motion pictures she's seen!" Though Hepburn never received royalties as an actress in the film, because she was a part investor, the film did provide a financial return for her (and still does for her estate).

Only someone like Cary Grant could have made this movie without being upstaged by Katherine Hepburn, but Grant was able to balance of comedy. This is about as good as an example of screwball comedy as you can get. A very funny movie.
